SAN D-BAND FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 429,654, dated June 10,1890.

Application filed March 8, 1890. Serial No. 343,209. (No model.)

To all whom it may concern:

Be it known that I, JOHN F. SMITH, a citizen of the United States,residing at Ionia, in the county of Ionia and State of Michigan, haveinvented certain new and useful Improvements in Sand-Bands for Vehicles;and

I do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to sand-bands for vehicles; and it consists of anouter and an inner shell that environ the axle and are adapted to besecured thereto, the outer shell adapted to snugly receive the innershell and to which it is slidingly coupled, a spring that encircles theaxle, located in the chamber between the two shells, the tension ofwhich holds a washer in the face of the outer shell against the innerface of the hub, the object being to provide simple and effective meansfor excluding sand or dust from the journal or wearing parts of theaxle. This object is attained by the device illustrated in theaccompanying drawings, in which Figure 1 is a side elevation of a huband a portion of the axle of a vehicle, showing my improved sand-bandattached thereto. Fig. 2 is a central vertical longitudinal sectionthrough Fig. 1. Fig. 3 is an enlarged view of the shells and spring,said parts being drawn apart.

Referring to the letters of reference, A indicates the hub of avehicle-wheel; B, the axle on which the hub is mounted; C and D, theshells forming the sand-band, and H the coiled spring located in thechamber between said shells. The shells O and D may be made of anysuitable metal. The shell D is formed in two parts, being dividedhorizontally through its center, as shown by line .9 in Fig. 3, and isprovided with the extended shank I), having a square openingtherethrough that is adapted to receive the square portion of the axleB, on which it is placed some distance back from the inner end of thehub. To accomplish this a division of the shell is necessary, as thesquare opening through said shell, to fit the axle snugly, is too smallto pass over the shoulder on the axle, against which the hub abut-s.Therefore the shell is formed in two parts, one part being placed on theaxle from below, and the other part from above. Said parts meet aroundthe axle and are secured thereto by the slip E, as shown in Figs. 1 and2. The annular rim of the shell D is provided with the raised flange 6,having the slots a a through its periphery, as shown in Fig. 3.

The inclosing-shell O is cylindrical in form and of such diameter as tosnugly receive the shell D within the chamber thereof, and is providedwith the elongated lugs a a, projecting from its inner face, that areadapted to lie in the slots a a of the flange e on the periphery of theshell D, whereby the inclosingshell 0 is locked from rotating, but ispermitted free longitudinal play, said shell 0 also having the flange 25extending diametrically from its interior wall some distance back fromits front or outer end, so as to form the recess '1: between said flangeand the outer end of said shell, in which to place the flexible wiper orwasher o, as shown in Figs. 2 and 3. The spring II is located in thechamber between the shells O and D and encircles the axle B, one end ofsaid spring bearing against the inner end of the shell D and the otherend against the flange t of the shell 0, whereby the tension-of saidspring will force the shell 0 outward, causing the washer U in the outerend of said shell to bear against the inner end of the hub A, as shownin Fig. 2. By this arrangement asthe hub revolves the spring holds thewasher o in continuous contact with the end thereof, and should there beend-play or a wabbling motion to the hub the spring will yield,permitting a longitudinal or rocking play to the shell 0, so that thewiper or washer 12 therein may at all times conform to the angle of theend of the hub, to the entire exclusion of all sand and dust from thewearing parts of the axle.

Having thus fully set forth my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In combination with the hub and axle of shell, the inclosing-shellhaving the lugs on a vehicle, the two-part shell made fast to the itsinner periphery and annular recess in its axle, the coiled springinclosed in said shell, front face, the washer therein, and the springthe inclosing shell slidingly coupled to the located between the shells,as specified.
